Bottle- Rockets and Planter

BOTTLE ROCKETS

for the past few weeks we have been working on bottle rockets which we then turned into planters.

our bottle rockets started as a normal bottle which we then hot glued fins onto before painting the whole thing. it took around 4 hours (4 periods) to complete but we got it done in the end. our bottle rocket was yellow with orange fins and i thought it looked pretty cool, we gave it a name which was fireball because my team thought it deserved a name.

when it came to flying it last Friday we used a wooden block which had an air pressure thing connected to it, we took the lid off our bottles to connect the pressure thing then pumped it until the rocket took off. our rocket didn't go very far the first time but because we knew what we did wrong we fixed it, did it again and it went much further.

TRANSFORMING MY ROCKET INTO A PLANTER.
After we had flown our rockets we ripped of the fins and the cone and cut it in half we then put felt through the bottle top opening and water in the bottom half of the bottle where we placed the top half on top so that the felt would transfer the water to the seeds.

We then put a small cotton bud over the felt so when we filled the bottle with a small beaker of rocks they wouldn't fall through.
Then we filled it with dirt near to the top and planted our radish seeds and watered it lightly.

1 week after planting the radishes they have sprouted
and started to grow.

Dry Ice

A couple of days ago in science class we did an experiment using the involvement of dry ice. we started by getting into small groups, filled our beaker up with a bit of water, using some tongs  we got our piece of dry ice, took it back over to the beaker, dropped it in and watched the magic happen.The dry ice started to bubble and you could pour it on the table and play with the steam like substance. I didn't  known much about dry ice before that experiment but it is for sure something I would like to do again. Would you do this experiment if you had a chance to?This image below is not my image because I didn't get a photo, it is one off the internet.
